` tain brush of thetypeV commonly employed for cleaning-automobiles. fY;

The invention has .for its object to provide a water motor drivenrbrushwhich shall be sturdy in construction, compact and easy to handle andcapable of manufacture at loT cost, i l. 1

One of the principal features ofthe invention consists in the provisionofa water motor casingof ellipsoidal or oval form whereby the same maybe easily grasped by the hand, this desirable form of casing beingpossible because of the novel form of water motor which I'have devised.The casing is made in two halves, one' of which has a pair of channelsthrough which water under pressure may pass for rotating a pair of waterwheels which serve to drive the brush.

The various novel features of the invention will appear from thedetailed description taken in connection with the accompanying drawingsforming part of this specification, and in which:

Figure 1 shows the improved device laid open by removal of one of thehalves of the casing;

' Fig. 2 is an elevational device;

Fig. 3 is a View similar to Fig. 1, but showing the other half of thecasing, and

Fig. 4 is a side elevation of one of the water wheels.

In the drawings, 5 indicates any suitable form of brush which isremovably secured to a shaft 6 which enters a pipe 7 having thereinadjacent its end a bearing 8 for supporting the shaft 6, the pipe beingpreferably lared as at 9 to facilitate the discharge of water onto thelbrush 5.

` The other end of the pipe is secured to a casing C of the water motor,said casing being of ellipsoidal form and consisting of two separablehalves 10 and 11 which may be provided with lugs 12 through whichsuitable securing means are adapted-t0 vbe passed to maintainthe jointsofthe casing watertight. The ends ofthe casing are-exteriorly .threadedas at =13 Awhereby pipe couplings 14 may bel screwed thereover :tofurther assist in making the jointsof the casing water tight.;l Intothese couplings are screwed the pipe 7 and pipe' lcthioughy which latterwater is conducted to thecasing, pipef7: serving 'as' 4a dischargepipe.;v

Water passes through the casing by tWo separate paths 16 and 17, thesepaths consti-` tuting channels inonly' one `of thehalves of the casing.-That-part ofthe casing between the channels 1 6 and 17 may'be'termed anabutment and asshown, the ends of the i same terminate shortof theends,ofthe casing. 'Water wheels 19 are arranged in each of the channels andareconne'ctedby a common shaft' 20 which extends transverselyl of and issupported by the abutment 18,1,and which is providedwith a' gear 21between said water wheels,-there1being ak cavity22 in the abutment intgwhich a part of the gear 21 extends.

The abutment 18 also forms avbearing for the shaft 6 which is prevented`from longitudinal movement relative thereto by a collar 23 aiiixed onthe shaft and the hubl 24 of the gear 25 also fixed on the shaft andmeshing with the gear 21.

Part 11 of the casing C as distinguished from the part 10 is notprovided with water passages but is merely recessed to receive the upperhalves of the water wheels, gears and shafts, as will be readilyunderstood. The meeting faces of the halves 10 and 11 are fiat.

The operation of the device may be briey described as follows: Waterunder pressure is conducted through the pipe 15 to the casing C where itdivides and follows the channels 16 and 17, and impinging against thewater wheels 19, causes the same to be rotated, consequently impartingrotation to the brush 5 through the shafts and gearing,

the waters again meeting at the discharge vend of the casing and beingdischarged onto the brush 5 through the pipe 7.

By providing a divided water channel as shown, the exterior of thecasing may be made in ellipsoidal form, this form allowing the device tobe easily held in the hand. Furthermore, by providing a pair ofchannels, the water wheels can be made of comparatvely small diameterand the entire motor J-fvefry simply; cheaply,fI and Vfstuifdil-yconstr'ttetl; The" btment :'18 Betti/'een the channels provides tWosolid points of support foi' the shaft Q ()the bearings of Which areeasily made. f` t Both halves 10 and, llofl thefhcasingf@ may be Castwith the channels and cavities simple but `:nime the f dit ant 'and@renee fie tel be {Hd yto the 'appended ufoh, seid 'eaeing constitutingivo fsepf ,e wives, eind said pe ecuerng ffny one 'of 'Seid htives endeonipfisng 'tivo @nenn-els tete-i* wh'ee spesedinfette eff said ehionlyl @ne of i Saidrhalv'es eist-ing V two vfh'nhel's vitipssingaroiiitlan fbiitnent, a water Wheel'disposed inl each of said obannels, a vshaftextending., etc-ross said abutmentund livig beringij therein, a; gear onseid ,shaftV bet-Ween said Wheels, the labutment l'lavlng a cavity forreceiving said gear, a
